To H/t [whom may (once/n .tle it known that ,l, Joint l t oxziimlabt, a citizen ol the l nited ,itates, residing at tv oli' ll bster (ivoves, in the county of ti uis and Hiale ol lllissouri, have, be rented certain new and nsetul lmprmen ients in .lhiublellall (on-traction, of which the following is a StiOt'lllt'ztllUtl.

This appliez lion is a division and a continuation of one, filed by me November 9. flt l l. ti erial f lo. 65%)..298.

This invention relates to eonrrelie bnih'lingi structures 1nd has particular reference to a construction in which concrete slabs and columns are united to form a wall having, an air-space therein and being particularly :nlaptcd for cold storage plants, l'tHltlOItt'llS, and the like.

in the construction ot',.oonrrete building's, it is e ential that secur: and durable junctures be made between the polumns and the wall slabs ol the structure.

ll is an object of this invention to provide a s-tlrueture of concrete buildirag elements, which cooperate and are iuterengaged to form a rigid, scour: and lasting combination of elements.

itinotluaobject is to provide a concrete building structure in which the general construction ol" the etio mratiug' uprights aiul wall slabs is generally improved.

l /ill] these objeets in. view, this invention (JliItSlt-tls' ot. the novel llOfll/llltr; ot construction and arrangement of 1 arts, as will be herein; altcr more fully descriltietl and pointed out in the claim.

in the areonumnyi11g drawings torming part of this s 'u'citicat'ion, in which likenumbers of reference denote like parts wherever they orcur. l ip'ure l is a side elevation ot part ol a wall embralying this invention and including two columns and wall slabs connerted therewith; Fig. i! is a sectional view on the line l ig. l; l ier. 3 is a sectional view on the line Zl----7l, l ig. 1; and Fig. 4 is a sectional view ot? a wall showing an alternate form ot the invention.

The panel ot. a wall. depicted in Fig. '1, eo'tislsts ot a pair of columns or uprights l and a plurality ot. vertirallyalismsed slabs E2. llaeh slab 3 is preferably molded with a reetamrula configuration and is provided with a pair oi" tlang'es or ribs that is ar ranged to extend vertirally on a tare thereol,

one tlane'e being lo rated at one end of said slab and the other llange being located at the other end of said slab. A rabbet l and rib 5 are provided on the top and bottom in position on top of another, the rib 5 on the bottom of the upper slab its in the rabbet 1 in the top of the lower slab and the rib F on the top of the lower slab fits in the rabbet l in the bottom of the upper slab, whereby said slabs are unitedby a rabbeted juncture. The slabs 2 are arrangei'l one on top oi another, as just described, in two vertical walls or rows, so that the tlanges 3 borne by the slabs 52 of one wall fit against the flanges borne. by the slabs 52 ot the other wall,

two wrlls ol slabs. The ends of the slabs 2 of each wall lit in grooves 7 in the sides of columns 1, and are thereby held in place. The columns 1 are preferably supported on a foundation 8, which extends underneath the lower slabs 2 of each wall. A rib 9 on said foundation tits in the rabbets t in the bottoms of the lower slabs 3 of each wall. it tlflhlltPtl, the :uljoining-edges of each two adjacent slabs 2 at each wall, and the ends ot said slabs may be buttered with grout just previous to the, placing of said slabs in position in the wall, so that, when said grout sets, said slabs are united integrally and said sltlllS and columns 1 are, also, united in- .l egra l ly. thus constituting a monolithic structure. The bottoms ot the lower slabs 2 of each wall may, also, be buttered with grout, which. when set, unites the lower slabs and foundation 8 integrally.

In the construction depicted in Fig. 4, one of the walls of slabs 2 is omitted entirely and a wall composed of a plurality of slabs 10 is substituted therefor. Said slabs 10 are preferably formed with a uniform thickness throughout and are arranged to fit against the flanges 3 on slabs whereby an air-space (3 is left, between the slabs 10 and 9, the ends of said slabs 1t) and 2 being held in grooves T in eolunms .l, as hereinalu'ive described.

T claim:

in concrete coustrurtimi, a pair of columns baring grooves, an outer series of slabs arranged in superimposed order, the slabs of said outer series ot slabs being formed at their abutting edges with tongue and rabbet t connections, an inner series of slabs spaced pt said slab, so that, when one slab is placed thereby leaving an air space (3 between the being arranged from the outer series and being arranged in superimposed order, the slabs of said inner series of slabs being formed at their abutting edges with tongue and rabbet connections, the ends of the slabs of both series of slabs in the grooves of the columns, the slabs of one series having flanges at the ends thereof which flanges abut the slabs of the other series, the flanges acting to hold the outer faces of the two series of slabs in engagement with the adjacent Walls formed by the grooves in the columns, the I slabs 01" said inner series of slabs being placed in position independently of the outer ser1es. 15 In testimony whereof I hereunto affix my signature in the presence of two witnesses.
